How to Calculate Payroll Hours & Overtime

Calculating gross pay from your hours worked is straightforward once you have decimal hours. Here's the exact process employers and payroll systems use to remain compliant under federal labor regulations.

1
Enter your hours worked Use decimal format (e.g., 40.5) or switch to HH:MM mode and enter hours and minutes directly.
2
Enter your hourly rate Type your regular hourly wage. The calculator supports any rate from federal minimum wage to professional billing rates.
3
Toggle overtime if needed Enable overtime for hours beyond 40 per workweek. The standard multiplier is 1.5× for eligible non-exempt employees under FLSA guidelines.
4
Read your gross pay instantly Gross pay, regular pay, overtime pay, and a full formula breakdown all appear instantly.
Gross Pay = (Regular Hours × Rate) + [Overtime Hours × (Rate × 1.5)] Example: 45 hrs worked at $20/hr = (40 × $20) + (5 × $30) = $800 + $150 = $950.00 gross pay

📊 Excel Formula: Gross Pay with Overtime

To automatically calculate gross pay with standard overtime (1.5× after 40 hours) in Excel or Google Sheets, use this formula where Cell A1 is total decimal hours and Cell B1 is the hourly wage:

=MIN(A1,40)*B1 + MAX(0,A1-40)*B1*1.5

How it works: MIN(A1,40) caps regular pay at 40 hours, while MAX(0,A1-40) isolates any overtime hours and multiplies them by your overtime rate.

Federal Compliance & Overtime Rules (FLSA)

Under the **Fair Labor Standards Act (FLSA)** enforced by the **U.S. Department of Labor (DOL)**, non-exempt covered employees must receive overtime pay for hours worked over 40 in a workweek. Overtime is paid at a rate not less than time-and-one-half (1.5×) their regular rate of pay. Some states, like California, enforce stricter daily overtime rules (e.g., overtime pay after 8 hours in a single workday).

Frequently Asked Questions

Common questions about payroll hour and gross pay calculations.

How do I calculate payroll from decimal hours?

Simply multiply your total decimal hours worked by your hourly rate. For example, if you worked 40.5 decimal hours at a rate of $20.00 per hour: 40.5 × $20 = $810.00 gross pay. For accurate payroll, avoid treating minutes as decimal values directly.

How is overtime pay calculated under FLSA rules?

Federal FLSA rules mandate paying standard overtime at 1.5× your regular hourly rate for hours worked beyond 40 in a single workweek. For example, if you worked 45 hours at $20.00/hour: your regular pay is 40 hours × $20 = $800, and your overtime pay is 5 hours × $30 (1.5 × $20) = $150, totaling $950.00 gross pay.

What is the difference between gross pay and net pay?

Gross pay is the total amount of money an employee earns before any tax withholdings, retirement contributions, or insurance deductions are taken out. Net pay (take-home pay) is the final amount an employee actually receives after all federal, state, and local taxes, Social Security (FICA), Medicare, and voluntary benefit deductions are subtracted.

How do I convert hours and minutes (HH:MM) to decimal hours for payroll?

To convert time card hours to decimal hours, divide the minutes by 60 and add them to the whole hours. For example, if you worked 7 hours and 45 minutes: divide 45 by 60 (45 ÷ 60 = 0.75) and add to 7, resulting in 7.75 decimal hours. You can switch to our calculator's HH:MM mode to perform this automatically.

What is double-time pay and when does it apply?

Double-time pay is a rate of compensation equal to twice (2.0×) an employee's regular hourly rate. Under federal FLSA law, double-time is not universally mandatory; however, it is commonly paid for work performed on major federal holidays, Sundays, or under state-specific laws (such as California, which mandates double-time pay for work exceeding 12 hours in a single workday or work beyond 8 hours on the 7th consecutive day of a workweek).
